Application filed June 11,

To all whom it may concern.

Be it known that 1, Litres F. Aimiis'rnoivo, a citizen of the UnitedStates of America, residing at Elgin, in the county of Antelope andState of Nebraska, have invented new and useful Improvements inFoot-Accelerator Attachments for Automobiles, of which.

" the iiollowing a specification.

The object of the invention is to proidde a simple and relativelyinexpensive toot accelerator attachment for supplementing the manuallyoperable accelerator in common use upon auton'iobiles of the Ford typein reference to the control oi the carburetter and adapt-ed to be usedwithout interfering with the operation of the means ordi arily employedfor this purpose and at the same time to permit of the operation of themanually controlled means in accordance with the usual practice and tothis end the same consists in a construction and combination of parts ofwhich a preferred embodiment is shown in the accompanying drawing,wherein:

Figure l is a perspective view showing the attachment applied in theoperative position to the related parts of the automobile.

Figure 2 is a view of the intermediate or transmission yoke.

The contemplated apparatus is designed for use in connection with theusual steering column 10 adjacent to which are arranged the carburetterrod 11 and spark rod 12 the former in the usual practice being di rectlyconnected with the carburettor 13 located in convenient relation to theengine 14, and in the present adaptation an operating arm 15 secured toand carried by the carburetter rod ll is arranged in operative relationwith an intermediate or transmission yoke 16, preferably tulcrumed as at17 upon the carburettor and spark rods in the path oil said arm 15, thesaid yoke being connected by a rod 18 with the czn'buretterlever 1.) tothe end that when the carburctter rod 11 turned in the ordinary way itwill act through the intermediate or transmission yoke 16 to ati'ect thecarburettor and regulate the amount or" supplied to the engine, saidyoke being yieldingly held in a normal position or in opposition to thepressure 01. the arm 15 by means of a spring 20.

The connection between the rod 18 and the yoke 16 is effected by meansof an eye 21' formed on the latter and consisting, when NEBRASFA.

the yoke as shown is constructed of a single length oit' wire or rod, oia looped portion thereof as indicated, and extending therefrom is alooped arm 22 serving as a bearing with which contacts the arm 15 in theordinary operation of the carburettor by means of the movement of thecarburetter rod 11.

l l ith an intermediate eye 23 also formed by coiling the od of whichthe yoke 16 is constructed, is the stem 24- ot a pedal 25 adapted to bedisposed in rear of the dashboard ot the car within convenient reach ofthe footof the operator or driver, so that the yoke may be moved in thedirection necessary to position the carburettor lever 19, bymanipulating either the carburettor rod 11 by hand as in the ordinarypractice, or by pressure upon the pedal 25 This arrangement enables theoperator to use the pedal in an emergency as in ascending a sharp gradeand where a rich mixture is desired only for a short period, withoutmodifying the adjustment ot the carburettor lever at the steering wheel,so that after the grade has been overcome or the necessity for theincreased speed or power no longer exists, the release of the pedal fromthe pressure of the foot will allow the carburetter through the actionof the spring 20 to return to the previous adjustment controlled by theposition of the hand operated means for regulating the carburetter.

In other words the foot operable attachment may be applied to a caralready equipped with the usual hand operated means for controlling thecarburettor and may be used independently thereof when an occasionarises for an abrupt increase in power or in the feed of fuel withoutalter ing the adjustment of the manually operable means which thus maybe set to secure the best results under normal conditions of load andspeed. and in this way the flexibility in the operation of the car isincreased and the operation thereof under varying conditions isfacilitated.

What is claimed is:

1. A toot control for carburetters consisting of a "foot actuableintermediate or trans mission yoke connected with the carburettor andarranged in the path of movement of an arm aotuable by the carburettorrod, said yoke consisting of a rod providedwith ter minal eyes forengagement with the car buretter and spark control rods of the steeringcolumn, intermediate eyes for connection respectively with thecurl'nlretter and a pedal stem, and a terminal arm for engagen'lent bythe arm. of the carburetter rod.

2. A foot control for cerbm'etters cons1st- 'ing of a foot aotua-bleintermediate or trans n'ussion yoke connected W1th. the carburettor yokebeing provided with. means for swinging connection with the cerbulretterand spark controlled rods oi. the steering column, means for operativeconnection with the carburetter and a foot pedal, and means foractuation by the carburett'er rod.

' In testimony whereof he affixes his signw ture.
